You are able to tame monstrous creatures like you would normal animals.
Prerequisite: Wild empathy ability.
Benefit: Choose a creature type other than animal, construct, humanoid, or undead. You can use your wild empathy ability to influence creatures of that type with an Intelligence of 3 or less. In addition, you no longer suffer a -4 penalty on your wild empathy checks to influence magical beasts.
Most monsters have a starting attitude of hostile.
Special: You can gain this feat multiple times. Each time you take the feat, it applies to a new creature type.
Normal: A character with wild empathy can usually only influence animals, or magical beasts at a -4 penalty.
